CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.16/120,033, entitled “INTRAVENOUS PRIMING CAP,” filed on Aug. 31, 2018,the entirety of which is incorporated herein by reference for allpurposes.

BACKGROUND

The present application relates to intravenous (IV) administration setsand devices used to administer fluids to a patient's vascular systemthrough a needle or catheter inserted into a vein. More specifically,the present application is directed to fluid connector caps that can beused to cover a fluid connector, permit fluid priming, and preventcontamination of a fluid connector and IV administration set.

IV administration sets are devices used to administer fluids from acontainer to a patient's vascular system through a needle or catheterinserted into a vein. IV administration sets can include a needle orLuer connector, IV line or tubing, a flow regulator, a drip chamber, aninfusion line filter, an intravenous set stopcock or valve, connectorsbetween parts of the set, access ports or injection sites, a clamp suchas a roller clamp, and an IV spike to penetrate and connect the tubingto an IV bag or other infusion fluid container.

SUMMARY

To prevent an air embolism, IV administration sets must be primed with afluid or IV solution to remove air from the tubing prior to attachingthe IV tubing to a patient. An air embolism is a potential complicationof IV therapy and can enter a patient's blood system through unprimed IVtubing, damaged or cut tubing, access ports, and drip chambers with toolittle fluid.

To prime an IV administration set, a clamp is positioned along the IVline below the drip chamber, and the clamp is moved to a closedposition. If present, the protective cover on the IV spike is removed,and the IV spike is inserted into an infusion fluid container. Theinfusion fluid container is hung or suspended, usually from an IV pole.The drip chamber can be squeezed or compressed to eject infusion fluidinto and partially fill the drip chamber with the infusion fluid.

The clamp is moved to an open position to permit the infusion fluid andgas or air to move through the IV line to the distal end of the IV line,e.g., and infusion fluid container. If a cap is affixed to the distalend of the IV line, or fluid connector at the distal end of the IV line,the cap is removed to permit fluid and gas to exit the IV administrationset.

To dispose of infusion fluid ejected from the IV line during priming,the distal end of the IV line can be held by a caregiver over a sink orbasin. The infusion fluid is permitted to drip from the distal end ofthe tubing until there are no large air bubbles in the intravascularadministration set. During priming of the IV administration set, acaregiver can also hold the distal end of the tubing in an invertedposition while the infusion fluid moves toward the distal end of thetubing and until no air bubbles remain in the tubing. After the IVadministration set is primed, the distal end of the tubing, or fluidconnector affixed thereto, must be covered to prevent contamination ofthe IV administration set.

Priming of an IV administration set can require the caregiver to holdthe distal end of the tubing in an inverted position for 10-30 seconds.This process of priming IV administration sets may be repeated manytimes per work shift and for multiple patients, preventing the caregiverfrom attending to other tasks, increasing the potential for errors suchas contamination of the IV administration set, and exacerbating therequired physical exertion, which can cause injury to the caregiver.

During preparation and priming, an IV administration set could becomecontaminated if a cap is removed from the distal end of the IV line orfluid connector, and the distal end of the IV line or fluid connectortouch the ground or another object. An IV administration set could alsobecome contaminated if a cap, removed from the distal end of the IV lineor fluid connector, becomes contaminated while removed and is thenreattached to the distal end of the IV line or fluid connector of the IVadministration set.

Priming of an IV administration set can cause the caregiver to beexposed to the intravenous fluid being ejected from the tubing. Exposureor contact with the intravenous fluid may be harmful to the caregiver,such as when the intravenous fluid is a toxic chemotherapy drugs for usein oncology. Harm from exposure may occur in a single instance ofexposure, or from repeated exposure to intravenous fluid.

In accordance with at least some embodiments disclosed herein is therealization that although a procedures can be implemented to preventcontamination of an IV administration set, certain problems occur whenan innumerable number of IV administration sets are implemented duringmedical procedures. For example, the IV administration set can becomecontaminated, and the contamination can be transferred to a patient whenthe IV administration set is primed and coupled to a patient'sintravascular system.

Some embodiments disclosed herein relate to the realization thatcountless IV administration sets are implemented by caregivers, who canbecome physically fatigued by repeated preparation and priming of IVadministration sets. Embodiments disclosed herein also relate to therealization that a caregiver can become injured from exposure to theinfusion fluid.

In accordance with at least some embodiments disclosed herein, thepresent disclosure provides IV priming caps that can preventcontamination of an IV administration set, ease physical exertion by acaregiver, reduce the time used by a caregiver for preparation andpriming of an IV administration, and prevent harm to a caregiver byexposure to infusion fluids.

Accordingly, the summary, drawings, and detailed descriptionare to be regarded as illustrative in nature and not as restrictive.

The detailed description set forth below is intended as a description ofvarious configurations of the subject technology and is not intended torepresent the only configurations in which the subject technology may bepracticed. The appended drawings are incorporated herein and constitutea part of the detailed description. The detailed description includesspecific details for the purpose of providing a thorough understandingof the subject technology. However, it will be apparent to those skilledin the art that the subject technology may be practiced without thesespecific details. In some instances, well-known structures andcomponents are shown in block diagram form in order to avoid obscuringthe concepts of the subject technology. Like components are labeled withidentical element numbers for ease of understanding.

In accordance with at least some embodiments disclosed herein is a IVpriming cap that can prevent contamination of an IV administration set,including preventing contamination that can occur during preparation ofan IV administration set and a patient, priming of the IV administrationset, and coupling of the IV administration set to the patient.

FIG. 1 illustrates a caregiver 10 and a patient 12. The patient isreceiving infusion fluid through and an IV administration set 20 coupledto the patient's vascular system. FIG. 2 illustrates an infusion fluidcontainer 22 and an IV administration set 20. The IV administration setincludes a drip chamber 24 coupled to the infusion fluid container 22,tubing of an IV line 26 with a proximal end coupled to the drip chamber24, and a distal end of the IV line 26 coupled to a fluid connector 28.A roller clamp 30 is coupled to a length of the IV line 26, between thedrip chamber 24 and the fluid connector 28. The fluid connector iscoupled to an IV priming cap 34, and the IV priming cap 34 is coupled toa length of the IV line 26, between the drip chamber 24 and the rollerclamp 30. In some embodiments, the IV priming cap 34 can engage orcouple with another portion of an IV administration set 20, such as theroller clamp 30 or an IV line pinch clamp, to hang the distal end of theIV line and fluid connector from the IV administration set.

The IV priming cap is configured so that the distal end of the IV lineand fluid connector are inverted relative to the orientation of theproximal end of the IV line when the IV priming cap is coupled to the IVadministration set. The inverted orientation of the distal end of the IVline and fluid connector facilitate priming of the IV administrationset.

The IV priming cap can coupled to the IV administration set using acoupling tab extending from the IV priming cap. The coupling tab can beconfigured with one or more arm forming any of a tubing passage and aslot.

The tubing passage and/or slot can include a width that permits couplingof the IV priming cap to a length of IV tubing without compressing theIV line such that a rate of fluid flow is not reduced therethrough.However, in some embodiments, the tubing passage and/or slot can includea width that causes the length of IV line to be compressed, therebycausing a rate of fluid flow to be reduced therethrough.

In some aspects of the present disclosure, a length of IV line iscompressed by an IV priming cap such that a rate of fluid flow throughthe IV line can permit priming of the IV administration set, however,said rate of fluid flow through the IV line is not sufficient toadminister the infusion fluid to the patient. As a result, the caregivercan prime the IV administration set with the IV priming cap attached tothe IV line, however, the caregiver may not achieve the desired flowrate for therapy. Because the desired flow rate is not achieved, thecaregiver is prompted to remove and/or discard the IV priming cap priorto administering the infusion fluid to the patient.

The IV administration set can be primed with the distal end of the IVline with fluid connector coupled to the IV priming cap, or the IVadministration set can be primed by separating the fluid connector fromthe IV priming cap. The IV priming cap can be separated from the IVadministration set and disposed of before or after priming the IVadministration set.

In some embodiments of the present disclosure, the IV priming cap canprovide an indication of priming, including an indication that priminghas occurred. For example, the IV priming cap can include a materialthat changes color to indicate that fluid has been ejected from the IVadministration set. In some embodiments, the IV priming cap includes ahydrophobic filter that can change color to indicate contact with aliquid. The IV priming cap can also provide an indication that the IVpriming cap remains coupled to the IV administration set. For example,the IV priming cap can be configured to restrict fluid flow through theIV line as an indication to remove the IV priming cap.

Although the present disclosure describes embodiments of an IV primingcap that can couple with a male luer-type fluid connector, it should beappreciated that the IV priming cap can be coupled with other fluidconnectors. However, for clarity and brevity, the present disclosurewill primarily refer to a male luer fluid connector. Additionally,although the present disclosure describes of an IV priming cap relativeto an IV administration set, it should be appreciated that the IVpriming cap can be coupled with other IV fluid delivery devices andsystems. However, for clarity and brevity, the present disclosure willprimarily refer to an IV administration set.

FIGS. 3A-3E illustrate an embodiment of an IV priming cap 100. The IVpriming cap can couple with a distal end of an IV line, or fluidconnector at the distal end of the IV line. In at least some embodimentsdisclosed herein, the IV priming cap could couple with a fluid connectorand a portion of an IV administration set to suspend the distal end ofthe IV line and fluid connector from the IV administration set.

The IV priming cap 100 includes a cover body 102 and a coupling tab 104.The cover body 102 includes a proximal end 106 and a distal end 108,opposite the proximal end 106. The cover body 102 includes an innersurface 110 defining a cavity extending into the cover body 102 andconfigured to receive a fluid connector therein. The cavity can extendfrom the proximal end 106 toward the distal end 108 of the cover body102. A longitudinal connector cavity axis 1A extends between theproximal end 106 and the distal end 108 of the cover body 102.

The cover body 102 has an outer surface with a cross-sectional profile,transverse to the longitudinal connector cavity axis 1A. As used in thepresent disclosure, the term transverse can include any direction orangle that can intersect or extend across another direction or angle.The cross-sectional profile of the cover body 102 can taper from theproximal end 106 toward the distal end 108. In some embodiments of thepresent disclosure, the outer surface of the cover body 102 has aproximal segment 112, extending from the proximal end 106 toward thedistal end 108, and a distal segment 114, extending from the proximalsegment 112 toward the distal end 108. The proximal segment 112 has afirst cross-sectional width, and the distal segment 114 has a secondcross-sectional width that is less than the first cross-sectional width.In some embodiments, the outer surface of the cover body 102 tapersbetween the proximal segment 112 and the distal segment 114.

The IV priming cap 100 can include ribs 116 protruding from the outersurface of the cover body 102, as shown in FIGS. 3A-3C. The ribs 116 canextend between the proximal end 106 and the distal end 108 of the coverbody 102. In at least some embodiments disclosed herein, the ribs 116extend along the distal segment 114, between the proximal segment 112and the distal end 108 of the cover body.

The ribs 116 can provide increased surface area and leverage forgrasping and rotating the IV priming cap 100 around the longitudinalconnector cavity axis 1A. The ribs 116 can also provide structuralrigidity and support along the proximal segment 112 and the distalsegment 114.

In some embodiments, the outer surface of the cover body 102 can includegrooves or channels that extend into the outer surface of the cover body102. In at least some embodiments of the present disclosure, the outersurface of the cover body 102 can include a concave portion, such as adimple or notch, a convex portion, such as a bulge or ridge, or anycombination thereof. Any of the concave and the convex surface featurescan increase the surface area of the outer surface area and increaserigidity of the cover body 102.

The inner surface 110 of the cover body can form a proximal cavity 120along the proximal segment 112 of the cover body, and a distal cavity122 along the distal segment 114 of the cover body, as best illustratedin FIG. 3E.

When the IV priming cap 100 is coupled with a fluid connector, differentportions of the fluid connector may engage the cover body 102 at theproximal cavity 120 and the distal cavity 122. In some examples, when amale luer connector is coupled with the IV priming cap 100, a bodyportion of fluid connector may be positioned within the proximal cavity120, and the male luer portion of the fluid connector may be positionedwithin the distal cavity 122. In an example, an outer surface of thefluid connector having a thread or other coupling feature can engage theinner surface 110 of the cover body along the proximal cavity 120. Whenthe coupling feature of the fluid connector is engaged against the innersurface 110 of the cover body along the proximal cavity 120, the maleluer portion of the fluid connector may engage against the inner surface110 of the cover body along the distal cavity 122.

The cover body 102 can include a wall 124 that extends from the distalsegment 114 into the proximal cavity 120, and around the connectorcavity axis 1A. An inner surface of the wall 124 can form a portion ofthe distal cavity 122. An outer surface of the wall 124 is spaced apartfrom the inner surface 110 of the cover body along the proximal segment112.

The distal cavity 122 has a cross-sectional width, formed between theinner surface of the distal cavity 122 and the wall 124. Thecross-sectional width of the distal cavity 122 can be configured toengage against a male luer of a fluid connector inserted into the cavityof the cover body 102. The cross-sectional width of the distal cavity122 can taper toward the distal end 108 of the cover body. In someaspects of the present disclosure, the IV priming cap 100 can fluidlyseal against a male luer of a fluid connector by forming an interferencefit between the male luer and the inner surface of the cover body 102along the distal cavity 122.

The cover body 102 can include a priming passage 126 to permit movementof a fluid between the cavity of the cover body 102 and an area adjacentto the outer surface of the IV priming cap 100. The priming passage 126extends between the distal cavity 122 and the distal end 108 of thecover body. In some embodiments, the priming passage 126 can extend fromany of the proximal cavity 120 and/or distal cavity 120 to an outersurface of the cover body 102. In some examples, the priming passage 126extends between the distal cavity 120 and an outer surface side surfaceof the cover body along the distal segment 114. In some embodiments, atleast a portion of the priming passage 126 can be formed by a grooveextending into the cover body 102.

The priming passage 126 permits priming of the IV administration setwithout separating or removing the IV priming cap 100 from the fluidconnector. As a result, infusion fluid and gasses can be directed out ofthe IV administration set through the fluid connector with the IVpriming cap 100 affixed thereto. Because the IV priming cap 100 does notneed to be removed or separated from the fluid connector during priming,the potential of contaminating the fluid connector or IV administrationset is reduced.

In at least some embodiments disclosed herein, the IV priming cap 100comprises a filter 128. The filter 128 is positioned along the primingpassage 126 to strain or separate a fluid moving therethrough. In someembodiments of the present disclosure, the filter 128 can provide anindication that the IV administration set has been used and/or primed.

The filter 128 can be positioned within the priming passage 126, orcoupled to a tip portion of the cover body 102. Referring to FIG. 3E,the IV priming cap can include a recess 130 to receive the filter 128therein. The recess 130 can extend into the distal end of the cover body102 and the priming passage 126 intersects the recess 130. In someembodiments, the IV priming cap does not include a filter. Inembodiments which do not include a filter, the priming passage canextend through the recess 130 (e.g., FIG. 4E).

The filter 128 can be configured to permit a gas to move through thefilter while resisting movement of a liquid through the filter. Forexample, the filter 128 can be a hydrophobic filter. In some examples,the filter 128 comprises polyethylene material, or comprises a membranecoated with polyethylene.

To provide an indication that the IV administration set has been usedand/or primed, the filter can comprise a color that changes. Forexample, the filter may change color when a liquid (e.g., infusionfluid) has contact against the filter.

At least some embodiments disclosed herein, the inner surface of thecover body 102 includes a ridge 134 configured to engage against a fluidconnector positioned within the cavity of the IV priming cap. The ridge134 can be formed as any of a helical ridge and a longitudinal ridge. Insome embodiments, the ridge 134 can be any shape configured to engagewith a fluid connector.

The helical ridge (e.g., FIGS. 3B and 3E) can be shaped as a threadalong the inner surface of the cover body. The thread can extend awayfrom the inner surface or into the inner surface 110 of the cover body.The thread can have a thread pitch configured to mesh with a thread of afluid connector coupled to IV priming cap.

The longitudinal ridge (e.g., FIGS. 4B and 4E) can be shaped as any of awall extending longitudinally along the inner surface of the cover body,and a groove or channel extending into the inner surface 110 of thecover body. In some aspects, a ridge can be formed between channelsextending into the inner surface 110 of the cover body. The longitudinalridge can be configured to engage against an outer surface of a fluidconnector coupled to IV priming cap.

In some embodiments of the present disclosure, any of the helical andlongitudinal ridge can be shaped as a plurality of plurality ofprotrusions in a helical or angular pattern relative to the connectorcavity axis A1, and can extend parallel with the connector cavity axisA1.

The cover body 102 can include a projection 138 extending into any ofthe proximal cavity 120 and the distal cavity 124. The projection 138can extend from the inner surface 110 of the cover body into theproximal cavity 120. FIGS. 3D and 3E, the projection 138 extends formthe inner surface 110, between the proximal segment 112 and the distalsegment 114 of the cover body. In some embodiments, projections 138 arespaced apart around the connector cavity axis A1.

The projection 138 can resist movement of a fluid connector, within theproximal cavity 120, in a direction toward the distal cavity 122. Insome aspects, the projection 138 can provide rigidity between theproximal segment 112 and the distal segment 114 of the cover body.

The coupling tab 104 of the IV priming cap 100 is generally shaped as aclamp extending from the cover body 102 to engage or couple with aportion of the IV administration set. When the coupling tab 104 iscoupled with the IV administration set, the distal end of the IV lineand fluid connector retained within the IV priming cap are covered toresist contamination from contact by a caregiver or patient. Further,the distal end of the IV line and fluid connector are suspended from theIV administration set, preventing contamination from contact with thefloor or ground. Further yet, the inverted orientation of the distal endof the IV line and fluid connector, when the IV priming cap is coupledto the IV administration set, facilitated priming of the IVadministration set.

The coupling tab 104 is shaped as a clamp having a first coupling arm140 and a second coupling arm 142. Each of the first coupling arm 140and the second coupling arm 142 include a base portion coupled to thecover body 102 and a tip portion distal to the cover body 102. Thecoupling tab 104 extends away from the cover body 102 in a directionthat is transverse relative to the connector cavity axis 1A.

Each of the first coupling arm 140 and the second coupling arm 142include an inner surface 144 facing toward the other of the firstcoupling arm 140 and the second coupling arm 142. The inner surface ofthe first coupling arm 140 and the second coupling arm 142 form a tubingpassage 146 therebetween, identified generally by the area in brokenlines in FIG. 3D.

The inner surface of the first coupling arm 140 and the second couplingarm 142 also form at least a portion of a slot 148, identified generallyby the area in broken lines in FIG. 3D. The slot 148 extends between thetubing passage 146 and the outer surface of the coupling tab 104 topermit a length of IV line to be moved into the tubing passage 146. Theslot 148 can also permit the coupling tab 104 to couple with anotherstructure. In some embodiments, the slot extends from a tip portiontoward the base portion of the coupling tab 104.

A portion of the inner surface of the first coupling arm 140 and thesecond coupling arm 142 along the slot 148 extends inward such that alength L1 between the inner surfaces 144 along the slot 148 is less thana length L2 between the inner surfaces 144 along the tubing passage 146.The length L1 can be approximately equal to or less than a diameter ofthe IV line. In use, the first coupling arm 140 and the second couplingarm 142 can be urged away from each other to permit a length of IVtubing to be moved through the slot and into the tubing passage 146.

A longitudinal tubing passage axis 1B extends through the tubing passage146 and is parallel to the longitudinal connector cavity axis 1A. Whenthe coupling tab 104 is coupled with a length of IV line, the length ofIV line will extend generally aligned along the longitudinal tubingpassage axis 1B, and the distal end portion of the IV line will begenerally aligned along the longitudinal connector cavity axis 1A. Insome embodiments, the longitudinal tubing passage axis 1B extends at anangle that is transverse relative to the connector cavity axis 1A,wherein transverse includes any angle that extends across the connectorcavity axis 1A.

In some embodiments of the present disclosure, the IV priming cap 200includes a coupling tab 204 having opposing coupling arms, asillustrated in FIGS. 4A-4E.

The IV priming cap 200 can include features similar to those describedwith reference to the IV priming cap 100 (FIGS. 3A-3E). As such, adescription of some similar features is not repeated herein for clarityand brevity. However, features described with reference to an embodimentof the present disclosure can be implemented with any embodiment of thepresent disclosure.

The IV priming cap 200 includes a cover body 202 and a coupling tab 204.The cover body 202 includes a proximal end 206 and a distal end 208,opposite the proximal end 206. The cover body 202 includes an innersurface 210 defining a cavity extending into the cover body 202 andconfigured to receive a fluid connector therein. A longitudinalconnector cavity axis 2A extends between the proximal end 206 and thedistal end 208 of the cover body 202.

The inner surface 210 includes ridges 234 configured to engage against afluid connector positioned within the cavity of the IV priming cap. Theridges 234 are shaped as longitudinal ridges that can create aninterference fit between the IV priming cap 200 and a fluid connectorinserted into the cavity. In some aspects, the ridges 234 are configuredto mate with or engage a slot of the fluid connector.

The ridges 234 extend between the proximal end 206 and the distal end208 of the cover body 202, and are aligned relative to a connectorcavity axis 2A. Each of the ridges 234 extend parallel to the connectorcavity axis 2A, however, in some embodiments, ridges 234 can extendtransverse to the connector cavity axis 2A. For example, ridges 234 canextend transverse to the connector cavity axis 2A to form a spiral ofridges along the inner surface.

The ridges 234 can be spaced apart from each other along the innersurface of the cover body 202. The ridges 234 are spaced apart with anequal distance between each longitudinal ridge 234. In some embodiments,however, the longitudinal ridges 234 can be spaced apart with adifferent distance between one or more ridge. Ridges 234 havingdifferent spacing therebetween can permit a fluid connector havingmating channels with similar spacing therebetween to be inserted intothe IV priming cap.

The ridges 234 comprise a height between the inner surface of the coverbody and an inner-most surface of each ridge 234, e.g., a surfaceclosest to the connector cavity axis 2A. One or more of the ridges 234can have different height relative to another longitudinal ridge 234.

Referring to FIG. 4D, the IV priming cap 200 can have ridges 234A havinga first height H1, and a ridges 234B having a second height H2, which isgreater than the first height H1. The ridges can be positioned so thatridges 234A having a first height H1 are positioned between ridges 234Bhaving a second height H2.

In some embodiments of the present disclosure, the ridges 234 can have aheight that increases or decreases between the proximal end 206 and thedistal end 208. For example, the height of the ridges 234, illustratedin FIG. 4E, decreases from the proximal end 206 toward the distal end208, such that a cross-sectional length between inner surfaces of theridges tapers away from the proximal end 206.

The coupling tab 204 of the IV priming cap 200 extends away from thecover body 202 in a direction that is transverse relative to theconnector cavity axis 2A. The coupling tab 204 has a first coupling arm240 and a second coupling arm 242, with the second coupling arm 242oriented opposite the first coupling arm 240 to form a lobster clawshape.

Each of the first coupling arm 240 and the second coupling arm 242include a base portion coupled to the cover body 202 and a tip portiondistal to the cover body 202. The first coupling arm 240 and the secondcoupling arm 242 have a width in a direction that is transverse to theconnector cavity axis 2A. The width of each of the first coupling arm240 and the second coupling arm 242 tapers from the base portion towardthe tip portion.

The base portion of the first coupling arm 240 and the second couplingarm 242 extends along the outer surface of the cover body 202 over anangle 2C around the connector cavity axis 2A. In some embodiments of thepresent disclosure, the angle 2C is at least about 90 degrees and/orless than or equal to about 180 degrees. In some embodiments, the baseportion extends along the outer surface of the cover body 202 over anangle of about 140 degrees around the connector cavity axis 2A.

The first coupling arm 240 and the second coupling arm 242 include aninner surface 244 facing toward the other of the first coupling arm 240and the second coupling arm 242. The inner surface of the first couplingarm 240 and the second coupling arm 242 form a tubing passage 246,identified generally by the area in broken lines in FIG. 4D. Alongitudinal tubing passage axis 2B extends through the tubing passage246. The longitudinal tubing passage axis 2B extends at an angle that isparallel relative to the longitudinal connector cavity axis 2A. In someembodiments, the tubing passage axis 2B extends at an angle that istransverse relative to the longitudinal connector cavity axis 2A. Thetubing passage 246 has a cross-sectional shape. The cross-sectionalshape can be any of a circle, an ellipse, a semicircle, and a polygon.In some embodiments, the tubing passage 246 has a diameter that is lessthan a diameter of the IV line so that the coupling tab 200 engagesagainst the IV line and resists movement between IV priming cap 200 andthe IV line.

The inner surface of the first coupling arm 240 and the second couplingarm 242 also form at least a portion of a slot 248, identified generallyby the area in broken lines in FIG. 4D. The slot 248 extends between thetubing passage 246 and the outer surface of the coupling tab 204. Theslot 248 is positioned so that a passage formed by the slot 248, betweenthe tubing passage 246 and the outer surface of the coupling tab 204.The slot 248 can extend from a tip portion toward the base portion ofthe first and second coupling arms 240 and 242.

A portion of the inner surface of the first coupling arm 240 and thesecond coupling arm 242 along the slot 248 extends inward such that alength between the inner surfaces 244 along the slot 248 is less than alength between the inner surfaces 244 along the tubing passage 246.

The first coupling arm 240 and the second coupling arm 242 include aproximal surface facing toward the direction of the proximal end 206,and a distal surface facing toward the direction of the distal end 208.The distal surface comprises a recessed surface 250 so that at least aportion of the perimeter of each coupling arm 240 and 242 comprises awall 252 that extends above the recessed surface 250. In someembodiments of the present disclosure, any of the proximal surface andthe distal surface of coupling arm 240 and 242 can include a recesssurface. The recessed surface 250 and wall 252 provide structuralrigidity while reducing the amount of material necessary to form thecoupling tab 204.

The tubing passage 246 and slot 248 permit a length of IV line to bemoved into the tubing passage 246. The tubing passage 246 and slot 248can also permit the IV priming cap 200 to be coupled with anotherstructure, such as a pole or clamp. When the coupling tab 204 is coupledwith a length of IV line, the length of IV line will extend generallyaligned along the longitudinal tubing passage axis 2B, and the distalend portion of the IV line will be generally aligned along thelongitudinal connector cavity axis 2A.

In some embodiments of the present disclosure, the IV priming cap 300includes a hook-shaped coupling tab 304, as illustrated in FIGS. 5A-5D.

The IV priming cap 300 can include features similar to those describedwith reference to other embodiments disclosed herein. As such, adescription of some similar features is not repeated herein for clarityand brevity.

The IV priming cap 300 includes a cover body 302 and a coupling tab 304.The cover body 302 includes a proximal end 306 and a distal end 308,opposite the proximal end 306. The cover body 302 includes an innersurface 310 defining a cavity extending into the cover body 302 andconfigured to receive a fluid connector therein. A longitudinalconnector cavity axis 3A extends between the proximal end 306 and thedistal end 308 of the cover body 302. The cover body 302 can alsoinclude ridges 334 that extend from the inner surface 310 into thecavity to engage against a fluid connector positioned within the cavityof the IV priming cap.

The coupling tab 304 of the IV priming cap 300 extends away from thecover body 302 in a direction that is transverse relative to theconnector cavity axis 3A. The coupling tab includes a base portioncoupled to the cover body 302 and a tip portion distal to the cover body302.

The base portion extends from the cover body 302 in a first direction,and the tip portion extends from the base portion in a second direction,which is different than the first direction. The first direction istransverse to the connector cavity axis 3A and extends away from theouter surface of the cover body 302. The second direction is alsotransverse to the connector cavity axis 3A, but extends toward the outersurface of the cover body 302. Together, the base portion and the tipportion form a hook-shaped coupling tab 304 having an inner surfaceforming a tubing passage 346 with a longitudinal tubing passage axis 3Btherethrough. The tubing passage axis 3B is parallel relative to thelongitudinal connector cavity axis 3A. In some embodiments, the tubingpassage axis 3B extends at an angle that is transverse relative to theconnector cavity axis 3A.

In some embodiments, the tubing passage 346 has a diameter that is lessthan a diameter of the IV line so that the coupling tab 304 engagesagainst the IV line and resists movement between IV priming cap 300 andthe IV line.

At least a portion of a slot 348 can be formed between the coupling tab304 and the cover body 302. More specifically, the slot 348 can beformed between the tip portion of the coupling tab 302 and an outersurface of the cover body 304. In some embodiments, the slot 348 extendsbetween the tubing passage 346 and the outer surface of the coupling tab304. The slot 348 is oriented to extend, between the tubing passage 346and the outer surface of the coupling tab 304, in a direction toward thebase portion of the coupling tab 304.

A cross-section of the coupling tab 304 is shaped as a wall having aheight and a width. The height of the coupling tab 304 extends between aproximal surface, facing toward the direction of the proximal end 306,and a distal surface, facing toward the direction of the distal end 308.Along the base portion of the coupling tab 304, the wall heightdecreases away from the cover body 302 from a first height H3 to asecond height H4. Along the tip portion of the coupling tab 304, thewall height increases toward the cover body 302, from the second heightH4 to a third height H5. The third height H5 is greater than the secondheight H4. In some embodiments, the third height H5 is between the firstheight H3 and the second height H4.

The width of the coupling tab 304 is less than the first height H3, thesecond height H4, and the third height H5. The narrow width of thecoupling tab 304, relative to the height, permits the coupling tab 304to be urged away from the tubing passage axis 3B when a length of IVline is moved through the slot 346 to the tubing passage 348. The tallheight of the coupling tab 304, relative to the width, provides a largeinner surface area of the coupling tab 304 to engage against the lengthof IV line is inserted into the tubing passage 348. Engagement of theinner surface of the coupling tab 304 resists sliding or movement of theIV line relative to the IV priming cap 300.

A tip portion of the coupling tab 304 can include a protrusion 360having outer surfaces that extend away from the outer surfaces of thecoupling tab 304. The protrusion 360 can be cylindrically shaped andextend longitudinally along the height of the coupling tab 304. In someembodiments, the protrusion 360 can comprise a cross-sectional shapethat includes any of a circle, an ellipse, a semicircle, and a polygon.A cross-sectional profile of the protrusion 360, transverse to thetubing passage axis 3B, comprises a width that tapers along the heightof the coupling tab 304. The width of the protrusion 360 tapers from aproximal end of the coupling tab toward a distal end of the coupling tab304.

The tubing passage 346 and slot 348 permit a length of IV line to bemoved into the tubing passage 346. The tubing passage 346 and slot 348can also permit the IV priming cap 300 to be coupled with anotherstructure, such as a pole or clamp. When the coupling tab 304 is coupledwith a length of IV line, the length of IV line will extend generallyaligned along the longitudinal tubing passage axis 3B, and the distalend portion of the IV line will be generally aligned along thelongitudinal connector cavity axis 3A.

Referring to FIGS. 6A-6D, an embodiment of an IV priming cap 400 havinga hook-shaped coupling tab 404 is illustrated. The IV priming cap 400can include features similar to those described with reference to otherembodiments disclosed herein. As such, a description of some similarfeatures is not repeated herein for clarity and brevity.

The IV priming cap 400 includes a cover body 402 and a coupling tab 404.The cover body 402 includes a proximal end 406 and a distal end 408,opposite the proximal end 406. An inner surface 410 of the cover body402 defines a cavity, which extends into the cover body 402 and isconfigured to receive a fluid connector therein. A longitudinalconnector cavity axis 4A extends between the proximal end 406 and thedistal end 408 of the cover body 402.

The coupling tab 404 of the IV priming cap 400 extends away from thecover body 402 in a direction that is transverse relative to theconnector cavity axis 4A. The coupling tab includes a base portioncoupled to the cover body 402 and a tip portion distal to the cover body402.

The base portion of the coupling tab 404 extends along the outer surfaceof the cover body 402 over an angle 4C around the connector cavity axis2A. In some embodiments of the present disclosure, the angle 4C is atleast about 10 degrees and/or less than or equal to about 90 degrees. Insome embodiments, the base portion extends along the outer surface ofthe cover body 402 over an angle of about 90 degrees around theconnector cavity axis 4A.

The base portion extends from the cover body 402 a first direction, andthe tip portion extends from the base portion in a second direction,which is different than the first direction. The first direction istransverse to the connector cavity axis 4A and extends away from theouter surface of the cover body 402. The second direction is alsotransverse to the connector cavity axis 4A, but extends toward the outersurface of the cover body 402. Together, the base portion and the tipportion form a hook-shaped coupling tab 404 having an inner surfaceforming a tubing passage 446 with a longitudinal tubing passage axis 4Btherethrough. The tubing passage axis 4B is parallel relative to thelongitudinal connector cavity axis 4A. In some embodiments, the tubingpassage axis 4B extends at an angle that is transverse relative to theconnector cavity axis 4A.

In some embodiments, the tubing passage 446 has a diameter that is lessthan a diameter of the IV line so that the coupling tab 404 engagesagainst the IV line and resists movement between IV priming cap 400 andthe IV line.

At least a portion of a slot 448 can be formed between the coupling tab404 and the cover body 402. More specifically, the slot 448 can beformed between the tip portion of the coupling tab 404 and an outersurface of the cover body 402. The slot 448 extends between the tubingpassage 446 and the outer surface of the coupling tab 404. In someembodiments, the slot 448 is oriented to extend, between the tubingpassage 446 and the outer surface of the coupling tab 404, in adirection toward the base portion of the coupling tab 404.

The coupling tab 404 is shaped as a wall having a height and a width.The height of the coupling tab 404 extends between a proximal surface,facing toward the direction of the proximal end 406, and a distalsurface, facing toward the direction of the distal end 408. Along thebase portion of the coupling tab 404, the width decreases away from thecover body 402. In some embodiments, the width increases toward thecover body 402 along the tip portion of the coupling tab 404.

The distal surface comprises a recessed surface 450 so that at least aportion of the perimeter of the coupling tab 404 comprises a wall 452that extends above the recessed surface 450. In some embodiments of thepresent disclosure, any of the proximal surface and the distal surfaceof coupling tab 404 can include a recessed surface. The recessed surface450 and wall 452 provide structural rigidity while reducing the amountof material necessary to form the coup

The tubing passage 446 and slot 448 permit a length of IV line to bemoved into the tubing passage 446. When a length of IV line is insertedthrough the slot 448 to the tubing passage 446, the rigidity of thecoupling tab 404, relative to the IV line, resists deformation or urgingof the coupling tab 404. Where the tubing passage 446 has across-sectional length that is less than a diameter of the IV line, thelength of IV line inserted into the tubing passage 446 is compressed.

The tubing passage 446 and slot 448 can also permit the IV priming cap400 to be coupled with another structure, such as a pole or clamp. Whenthe coupling tab 404 is coupled with a length of IV line, the length ofIV line will extend generally aligned along the longitudinal tubingpassage axis 4B, and the distal end portion of the IV line will begenerally aligned along the longitudinal connector cavity axis 4A.

In some embodiments of the present disclosure, the IV priming cap 500includes a clip-shaped coupling tab 504, as illustrated in FIGS. 7A-7D.

The IV priming cap 500 can include features similar to those describedwith reference to other embodiments disclosed herein. As such, adescription of some similar features is not repeated herein for clarityand brevity.

The IV priming cap 500 includes a cover body 502 and a coupling tab 504.The cover body 502 includes a proximal end 506 and a distal end 508,opposite the proximal end 506. The cover body 502 includes an innersurface 510 defining a cavity extending into the cover body 502 andconfigured to receive a fluid connector therein. A longitudinalconnector cavity axis 5A extends between the proximal end 506 and thedistal end 508 of the cover body 502.

The coupling tab 504 of the IV priming cap 500 extends away from thecover body 502 in a direction that is transverse relative to theconnector cavity axis 5A. The coupling tab includes a base portion 562coupled to the cover body 502, a middle portion 564 extending from thebase portion and distal to the cover body 502, and a tip portion 566extending from the middle portion.

The base portion 562 extends from the cover body 502 in a firstdirection, which is transverse to the connector cavity axis 5A andextends away from the outer surface of the cover body 502. The middleportion 564 extends from the base portion 562 in a second direction,which is different than the first direction. The tip portion 566 extendsfrom the middle portion 564 in a third direction, which is differentthan the first and second direction. In some embodiments, the thirddirection is also transverse to the connector cavity axis 5A, butextends toward the outer surface of the cover body 502.

The base portion 562, the middle portion 564, and the tip portion 566form a clip-shaped coupling tab 504 having an inner surface forming atubing passage 546 with a longitudinal tubing passage axis 5Btherethrough.

The second direction can be any of parallel and transverse to theconnector cavity axis 5A. In embodiments where the second direction isparallel to the connector cavity axis 5A, the tubing passage axis 5B istransverse to the connector cavity axis 5A. In embodiments where thesecond direction is transverse to the connector cavity axis 5A, thetubing passage axis 5B is parallel to the connector cavity axis 5A.

A distance between the outer surface of the cover body 502 and the innersurface of the middle portion 564 is less than a diameter of the IV lineso that the coupling tab 500 engages against the IV line and resistsmovement between IV priming cap 500 and the IV line.

At least a portion of a slot 548 can be formed between the coupling tab504 and the cover body 502. More specifically, the slot 548 can beformed between the tip portion of the coupling tab 504 and an outersurface of the cover body 502. The slot 548 extends between the tubingpassage 546 and the outer surface of the coupling tab 504. The slot 548is oriented to extend, between the tubing passage 546 and the outersurface of the coupling tab 504, in a direction toward the base portionof the coupling tab 504.

The coupling tab 504 is shaped as a wall having a height, a width, and alength. The height of the coupling tab 504 extends between a proximalsurface, facing toward the direction of the proximal end 506, and adistal surface, facing toward the direction of the distal end 508. Thelength of the coupling tab 504 is a direction from the base portion 562to the tip portion 566, and the width of the coupling tab 504 is adirection transverse to the length of the coupling tab 504.

Any of the base portion 562, the middle portion 564, and the tip portion566, can have a height that decreases along of a length of therespective portion. The base portion 562 can have a height H10, and thetip portion 566 can have a height H12, which is less than the heightH10. Between the base portion 562 and the tip portion 566, the middleportion 564 comprises a height that decreases from the height H10 to theheight H12.

The width of the coupling tab 504 is less than the height H10 and theheight H12. The width of the coupling tab 504 and the reduced height ofthe tip portion 566, relative to the base portion 562 provides acoupling tab 504 that is more flexible in an area adjacent the tipportion 566, relative to an area adjacent the base portion 562. Theflexibility of the tip portion 566 can permit the tip portion 566 to beflexible and moved away from the cover body 502, while the less flexiblebase portion 562, relative to the tip portion 566, resists damage to theIV priming cap 500 when the coupling tab 504 is coupled to an IV line orother structure.

The tall height of the coupling tab 504, relative to the width, providesa large inner surface area of the coupling tab 504 to engage against thelength of IV line is inserted into the tubing passage 548. Engagement ofthe inner surface of the coupling tab 504 resists sliding or movement ofthe IV line relative to the IV priming cap 500.

The length L10 of the coupling tab 504 is less than the cross-sectionallength L12 of the cover body 502 adjacent the proximal end 506. Thelength L10 of the coupling tab 504 is approximately equal to the heightH10 of the base portion 562. Because the length L10 of the coupling tab504 is approximately equal to the height H10 of the base portion 562,the coupling tab 504 is less flexible, in a direction toward or awayfrom the cover body 502, relative to a coupling tab 504 having a lengththat is greater than length L10.

A tip portion of the coupling tab 504 can include a protrusion 560having outer surfaces that extend away from the outer surfaces of thecoupling tab 504. The protrusion 560 can be cylindrically shaped andextend longitudinally along the height of the coupling tab 504. In someembodiments, the protrusion 560 can comprise a cross-sectional shapethat includes any of a circle, an ellipse, a semicircle, and a polygon.In some embodiments, a cross-sectional profile of the protrusion 560,transverse to the tubing passage axis 5B, comprises a width that tapersalong the height of the coupling tab 504.

The tubing passage 546 and slot 548 permit a length of IV line to bemoved into the tubing passage 546. The tubing passage 546 and slot 548can also permit the IV priming cap 500 to be coupled with anotherstructure, such as a pole or clamp. When the coupling tab 504 is coupledwith a length of IV line, the length of IV line will extend generallyaligned along the longitudinal tubing passage axis 5B, and the distalend portion of the IV line will be generally aligned along thelongitudinal connector cavity axis 5A.

In some embodiments of the present disclosure, an IV priming cap 500includes an elongated clip-shaped coupling tab 504, as illustrated inFIGS. 8A-8D. The elongated coupling tab 504 includes a long lengthrelative to the height of the coupling tab 504.

The base portion 562 has a height H10, and the tip portion 566 can havea height H14, which is less than the height H10 and height H12. Betweenthe base portion 562 and the tip portion 566, the middle portion 564comprises a height that decreases from the height H10 toward the heightH14. In some embodiments, the height H10 of the base portion 562 is lessthan the height H14 of the tip portion 566, and a height of the middleportion 564 can increase from the height H10 toward the height H14.

The length L14 of the elongated coupling tab 504 is approximately equalto the cross-sectional length L12 of the cover body 502 adjacent theproximal end 506. The length L14 of the coupling tab 504 is greater thanthe height H10 of the base portion 562. In some embodiments, the lengthL14 of the coupling tab 504 twice as long as the height H10 of the baseportion 562.

Because the length L14 of the elongated coupling tab 504 is greater thanthe height H10 of the base portion 562, the elongated coupling tab 504is more flexible, in a direction toward or away from the cover body 502,relative to a coupling tab 504 having a length that is less than orequal to the height H10

Because the elongated coupling tab 504 is more flexible, a length of IVline positioned between the cover body 502 and the elongated couplingtab 504 may not be compressed, thereby permitting unobstructed flowthrough the IV line. Additionally, the elongated coupling tab 504 can beused to couple the IV priming cap to other structures, such a railing.

Referring to FIGS. 9A-9D, another embodiment of an IV priming cap 600having a clip-shaped coupling tab 604 is illustrated. The IV priming cap600 can include features similar to those described with reference toother embodiments disclosed herein. As such, a description of somesimilar features is not repeated herein for clarity and brevity.

The IV priming cap 600 includes a cover body 602 and a coupling tab 604.The cover body 602 includes a proximal end 606 and a distal end 608,opposite the proximal end 606. An inner surface 610 of the cover body602 defines a cavity, which extends into the cover body 602 and isconfigured to receive a fluid connector therein. A longitudinalconnector cavity axis 6A extends between the proximal end 606 and thedistal end 608 of the cover body 602.

The coupling tab 604 of the IV priming cap 600 extends away from thecover body 602 in a direction that is transverse relative to theconnector cavity axis 6A. The coupling tab includes a base portion 662coupled to the cover body 602 and a tip portion 666 that extends fromthe base portion 662. The base portion 662 extends from the cover body602 a first direction, and the tip portion 666 extends from the baseportion 662 in a second direction, which is different than the firstdirection.

The coupling tab 604 includes a side surface extending along the baseportion 662 and the tip portion 666. At least a portion of the sidesurface of the base portion 662 and the side surface of the tip portion666 face opposite to each other and are spaced apart to form a tubingpassage 646.

The tubing passage 646 extends through the coupling tab 604, between aproximal surface, facing toward the direction of the proximal end 606,and a distal surface, facing toward the direction of the distal end 608.The tubing passage 646 is oriented through the coupling tab 604 to forma longitudinal tubing passage axis 6B that is parallel relative to thelongitudinal connector cavity axis 6A. In some embodiments, the tubingpassage axis 6B extends at an angle that is transverse relative to theconnector cavity axis 6A. Additionally, the side surfaces of the baseportion 662 and the tip portion 666 form a slot 648. The slot 648extends between the tubing passage 646 and the outer surface of thecoupling tab 604.

The side surfaces side surfaces of the base portion 662 and the tipportion 666 that form the slot 648 and the tubing passage 646 canextends generally parallel to each other, taper toward each other, andtaper away from each other.

Referring to FIG. 9C, the width between the side surfaces of the baseportion 662 and the tip portion 666 can decrease along a first length toform a tapered slot 648. The width between the side surfaces thenincreases from the slot 648 to the tubing passage 646.

The width between side surfaces side surfaces of the coupling tab 604that form the tubing passage 646 and the slot 648 can be less than adiameter of the IV line so that length of IV line is compressed whenmoved into the tubing passage 648.

The distal surface comprises a recessed surface 650 so that at least aportion of the perimeter of the coupling tab 604 comprises a wall 652that extends above the recessed surface 650. In some embodiments of thepresent disclosure, any of the proximal surface and the distal surfaceof coupling tab 604 can include a recessed surface. The recessed surface650 and wall 652 provide structural rigidity while reducing the amountof material necessary to form the coupling tab 604.

The base portion 662 extends along the outer surface of the cover body602 over an angle 6C around the connector cavity axis 6C. In someembodiments, the base portion extends along the outer surface of thecover body 602 over an angle of about 90 degrees around the connectorcavity axis 6A.

The tubing passage 646 and slot 648 permit a length of IV line to bemoved into the tubing passage 646. When a length of IV line is insertedthrough the slot 648 to the tubing passage 646, the rigidity of thecoupling tab 604, relative to the IV line, resists deformation or movingof the coupling tab 604.

In use, a length of IV line is compressed as it is moved along thenarrowing portion of the slot 648 and into the tubing passage 646 of theIV priming cap 600 (FIG. 12 ). The cross-sectional width of the tubingpassage 646 can be configured to completely or partially occlude thefluid passage through the IV line.

Referring to FIGS. 10A-10D, another embodiment of an IV priming cap 700having a hook-shaped coupling tab 704 is illustrated. The IV priming cap400 can include features similar to those described with reference toother embodiments disclosed herein. As such, a description of somesimilar features is not repeated herein for clarity and brevity.

The IV priming cap 700 includes a cover body 702 and a coupling tab 704.The cover body 702 includes a proximal end 706 and a distal end 708,opposite the proximal end 706. An inner surface 710 of the cover body702 defines a cavity, which extends into the cover body 702 and isconfigured to receive a fluid connector therein. A longitudinalconnector cavity axis 7A extends between the proximal end 706 and thedistal end 708 of the cover body 702.

The coupling tab 704 of the IV priming cap 700 extends away from thecover body 702 in a direction that is transverse relative to theconnector cavity axis 7A. The coupling tab includes a base portion 762coupled to the cover body 702 and a tip portion 766 distal to the coverbody 702.

The base portion 762 extends from the cover body 702 a first direction,and the tip portion 766 extends from the base portion 762 in a seconddirection, which is different than the first direction.

The first direction is transverse to the connector cavity axis 7A sothat the base portion 762 extends away from the outer surface of thecover body 702. The second direction is different than the firstdirection so that the tip portion 766 extends along the outer surface ofthe cover body 702. In some embodiments, the second direction isparallel relative to the connector cavity axis 7A. In some embodiments,the second direction is any angle that is transverse relative to thefirst direction.

The tip portion 766 is spaced apart from the cover body 702 forming aslot 748 between an outer surface of the cover body 702 and innersurfaces of the base portion 762 and the tip portion 766.

The slot 748 extends between the cover body 702 and the tip portion 766,in a direction from the base portion 762 toward the proximal end 706 ofthe cover body 702. Additionally, the slot 748 extends laterally,relative to the connector cavity axis 7A.

In use, the IV priming cap 700 can be coupled to a structure, such as aroller clamp 30 (FIG. 2 ) or a pinch clamp 36 (FIG. 11 ). For example,referring to FIGS. 10D and 11 , the IV priming cap 700 is coupled to thepinch clamp 36 by moving the IV priming cap 700 toward the pinch clamp36 until the coupling tab 704 engages a portion of the pinch clamp 36 inthe slot 748.
